Answer:

Domain is (-∞, ∞)

Step-by-step explanation:

Given function is [tex]\sqrt[3]{5x+25}[/tex]

Please remember, for any cube root function the domain is all real numbers, because the cube root of any real number is a real number.

So, domain is all real numbers.

We can write it in interval notation as (-∞,∞).

The mathematical expression for "63 less than twice Julie's height"

is 2j - 63

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:

Expression: (Math Operator, Number/Variable, Math Operator)

We have,

63 less than twice Julie's height.

let the height of Julie be j.

Then, the mathematical expression for

"63 less than twice Julie's height"

= 2j - 63

Answer:

[tex]180.49[/tex]

Step-by-step explanation:

SOH-CAH-TOA:

In right triangles only:

The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)

The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)

Since we're given an angle, its opposite side, and its adjacent side, we'll use tangent to solve for [tex]x[/tex]:

[tex]\tan 14^{\circ}=\frac{45}{x},\\x=\frac{45}{\tan 14^{\circ}},\\x\approx \boxed{180.49}[/tex].

Answer:

-6

Step-by-step explanation:

We know that the equation is f(x)=-3x^2-3x.

This means when we plug -2 in, the equation will be f(-2)=-3(-2)^2-3(-2). Simplify this to get -3(4)+6. Simplify this to get -12+6 which is equal to -6. Therefore, f(-2)=-6

Answer:

B

Step-by-step explanation:

Substitute x = 11 into the expression

5(11 - 2)

= 5 × 9

= 45 → B

Answer:

45

Step-by-step explanation:

A function is given to us .And we need to find its value at x = 11. So on substituting x = 11 , we have ,

The given function :-

[tex]:\implies[/tex] f(x) = 5(x-2)

On putting x = 11 :-

[tex]:\implies[/tex] f(11) = 5 ( 11 - 2)

[tex]:\implies[/tex] f(11) = 5 × 9

[tex]:\implies[/tex] f(11) = 45

Answer:

The correct answer is choice D.

Step-by-step explanation:

Since the parabola opens sideways, that means the function will feature [tex]y^2[/tex] and not [tex]x^2[/tex], so you can immediately rule out options B and C. Because the graph also opens right, that means the coefficient of [tex]y^2[/tex] is positive. Using all of this information, you'll find that the correct answer is D: [tex]x = \frac{1}{12} y^2[/tex].

Answer:

B and C

Step-by-step explanation:

First, we need to get the left side equal to zero. Take away 25 from each side to get [tex]4x^2+12x-16 = 0[/tex].

We can use the quadratic equation of [tex]\frac{-b+ -\sqrt{b^2-4ac} }{2a}[/tex] to find the solutions.

Plug them in to get [tex]\frac{-12+-\sqrt{144 -(-256)} }{8}[/tex].

Simplify.

[tex]\frac{-12+-\sqrt{400} }{8}[/tex]

[tex]\frac{-12+-20}{8}[/tex]

[tex]\frac{8}{8}[/tex] or [tex]\frac{-32}{8}[/tex]
